The deadly explosions in Poland are now believed to be the result of missiles fired by Ukraine, according to a briefing by U.S. officials to the Associated Press. The officials said preliminary investigations suggest it was most likely Ukrainian anti-aircraft missiles or missiles going off course that were fired at an incoming Russian assault. Deferring a conclusion until investigations are complete, Joe Biden said “It is unlikely in the lines of the trajectory that it was fired from Russia, but we’ll see.” Polish President Andrzej Duda said, “We are acting with calm. This is a difficult situation.”
